Fun game :) I think it would be nice to be able to hold down a button to shoot. The aiming seemed a little misaligned and I had to adjust awkwardly to hit the enemies. Overall though I enjoyed it. The ability to combine upgrades was very cool!
I had some trouble running this game - it seems the game defaults to your native monitor resolution. Since I have an ultrawide monitor, all the dialogue and game instructions were cut off on the bottom of the screen. :(
